| 摘 要： | 建立了QuEChERS-温控离子液体分散液液微萃取结合高效液相色谱法快速检测脐橙中5种染色剂残留的分析方法。QuEChERS前处理步骤:样品用乙腈快速提取,NaCl和无水MgSO4除水后,经N-丙基乙二胺净化。温控离子液体分散液液微萃取步骤:QuEChERS前处理的净化液(1 mL)为分散剂,1-辛基-3-甲基咪唑六氟磷酸盐离子液体(60μL)为萃取剂,55℃水浴12 min,将目标物富集。用高效液相色谱-紫外检测器分析,检出样品用超高效液相色谱-串联质谱确证。在0.01和0.05 mg/kg的添加水平下,5种染色剂的平均回收率为70.3%~93.6%,相对标准偏差为3.5%~9.2%,定量限为1.1~2.8μg/kg。
